What app do you use to write?

Rings with all nonzero elemnts invertable go brrrrrrrr

Replace Laplace transform with Fourier transform and your video might actually be good

But isn't the real challenge in finding the potential energy in a specific problem?

Just do static analysis and oversizing comes with experience dont need differential equations

0-0

i love you

beautiful! thank you for making this

I wish my professors were this good at explaining

Why should we take 2nd derivative??

great remedy of insomnia

Can you explain why the standard Lagrangian is T-U? Intuitively, why that specific form (other than 'because it works')? Thanks

Thats just fcking great!

One of the best explanations on this topic

Thanks a lot, sir!

"There's a good chance you've run into this equation before." My man, its 11PM and I'm eating a donut on my kitchen counter. Not only have I not run into that equation before, but in an hour it is going to be replaced with more math I can't do, a video about a cool rock, or documentary about a country I ain't ever gonna go to. Simple Harmonic Oscillators look like they kick all kinds of ass but I am up too late looking for answers to problems that differential equations can't solve. Do not underestimate how dumb I am.

Here before this channel gets millions and millions of subscribers. Keep doing these animations, they are invaluable when you show the concepts. It really helps visualising the physics and the math.

My teacher said I dont need to study lagrangian until I can get into APhO😂

E=mc^2 Schwarzschild radius

It seems I can win Nobel prize if I take your course.

I have just found this channel, weeks before QM exams. Your videos really helps to patch the fragments. Thank you the video!

Anyone else still have no clue?

Great1

im starting quantum theory 1 now and the next video could really help!

The only problem is that the hamiltonian is not always equal to the total energy.

What are you talking about?

Why do we use dot notation to regard n-th order differentials instead of the standard apostrophe "prime" such as f'(x)?

Man this is high quality, easy some of the best physics educational content on youtube. Do you still plan on uploading any problem sets for this video? Thanks a lot for the notes btw

You got to be some kind of big idiot to be surprised still how nature works!

This just made my head hurt

Im fking enlightened

Thank you so much sir for this video ❤✨

Why normalised wf is required??

ah, yes, one of the most known engineering theorems: sin T = T

Amazing, thank you so much. It was music to the ears listening to you!

MashaAllah

So... You don't need calculus unless you want to find a particle. Ok, wasted a year in school 😂😂😂

Great video thanks, very clear and engaging

Lagrangian is sick

I'm gonna do u the good of telling u why I can't hang: u called Newton's interpretation of his share of facts "nonsense", as if u with the same facts could've done better. Look up the words "intellectual" and "hubris", then have a think.

Hate to be a hater, but I find the explanation in this video to be lacking and circular. Okay, so we're going to pull out this factor (1/ih_bar) and this here is a quantum generator(because it just is), and now that we've pulled out of our hat that it's the quantum generator, it should be momentum. For me, Dirac's approach of getting the quantum Poisson bracket from the classical one is much more satisfying and then using the canonical commutation relations you got from that you find the translation operator and all the other stuff you want.

On a xyz graph, a point is potential energy. Time is kinetic energy when going to another point. This existence is amplitude and is nested between another reality made up of shattered pieces.

Thanks for your interesting article. My intuition said there is something important about this mechanical effect. This model shows how a field represented by a sheet of elastic material under the right initial conditions naturally form quantized energy levels. From there it was easy to form very stable three dimensional structures using a very minimal amount of material. (similar to the way engineers built large light weight space structures) czcams.com/video/wrBsqiE0vG4/video.htmlsi=waT8lY2iX-wJdjO3 You and your followers might find the quantum-like analog useful in visualize nature properties of fields. I have been trying to describe the “U” shape wave that is produced in my amateur science mechanical model in the video link. I hear if you over-lap all the waves together using Fournier Transforms, it may make a “U” shape or square wave. Can this be correct representation Feynman Path Integrals? In the model, “U” shape waves are produced as the loading increases and just before the wave-like function shifts to the next higher energy level. Your followers might be interested in seeing the load verse deflection graph in white paper found elsewhere on my CZcams channel. Actually replicating it with a sheet of clear folder plastic and tape and seeing it first hand is worth the effort.

Oh my God, heroes see the same thing. When I decided to teach my son physics, the first thing I did was teach him solar system, Euler's formula, the Fourier transform, basically the circle.

Why can’t I use sin theta in the final equation? Or does it not make a difference, or am I just blind and short circuiting when doing the second derivative?

Great explained thanx

I'm so grateful for this video. I've been trying to self-study Differential Equations and kept getting stuck early on. This really helped clarify not only what to do to solve Differential Equations but WHY the methods work. Thank you!

Symmetry groups are the universe. The universe, in my view, a mathematical truth/structure. It (reality) is what happens when you have these mathematical objects called quantum fields defined on a manifold (spacetime) in some type of initial ordered/low entropy state. In theory all possible self consistent mathematical structures exist, so a structure with interacting quantum fields defined on a manifold with more than 3 spatial dimensions can’t exist as any interactions in 4 or more spatial dimensions lead to non-renormalizability, meaning the math becomes nonsensical and inconsistent so it can’t occur. But one in 2 spatial dimensions probably could, in 3 or less spatial dimensions qft’s can be interacting and renormalizable (meaning they are predictive).
